PGD (Preimplantation genetic diagnosis)

Preimplantation genetic diagnosis (PGD) involves screening single cells from embryos for genetic diseases and chromosomal disorders. This testing is performed with in-vitro fertilization (IVF) and occurs prior to embryo transfer, before a pregnancy is established. PGD offers at-risk couples the opportunity to select embryos for transfer based on their genetic and chromosomal status.  The goal of PGD is to identify abnormal embryos so they will not be transferred, leaving unaffected embryos to be selected for transfer that are more likely to make healthy, disease-free babies
